The Top 10 Reasons to use composite plastic bearings Composite plastic bushings combine thermoplastics, fibrous reinforcements, and solid lubricants for tailored bearing solutions with predictable lifetime in a wide variety of applications. These bushings run without maintenance, external lubrication, resist corrosion and debris, fit precisely with little creep, conduct heat efficiently, and dampen vibrations while maintaining high compressive strength. Read on for the top ten reasons to consider plastic bearings. 1. Lighter weight than metallic bearings Swapping metallic plastic bushings to composite plastic bushings can reduce weight by 25% or more. The difference in density between composite plastic materials and metals - 1 to 3 g/cm 3 vs. 7 to 9 g/cm 3 - the weight reduction available with plastic bearings is obvious. 2. Corrosion resistance Metal-free iglide ® plastic bearings do not rust, and most available materials will not corrode in acidic or basic solutions, or when exposed to traditional lubricants. The iglide ® product line also includes bearings that are able to resist harsh acids, such as hydrochloric acid, as well as UV and other high-energy radiation. Chemical resistance can change with temperature and chemical concentration, so be sure to take your specific application conditions into account. 3. 100% self-lubricating iglide ® plastic bearings are designed to run dry, without any external lubrication. Fiber reinforcements create millions of tiny chambers, which house particles of solid lubricant which are released as friction against a shaft occurs. Homogeneous blending of the plastic material means that lubricant cannot be pressed out, and will last throughout the entire service life of the bearing. 4. Forgiving of shock and edge loads; vibration dampening Plastic bearings run quietly and absorb or dampen vibrations. Their mechanical loss factor, and indicator of vibration-dampening capability, is up to 250 times that of metallic bearings. The fiber-reinforced material blends are tailored to specific application requirements, helping bearings stand up to shock and edge loads in a wide range of application settings.
